If you've played the game you may have noticed that before the first sequence with Scarecrow there is a man talking on the monitors about Arkham's affordable prices he gives a website to find the prices at http://www.arkhamcare.com/prices
and from that you can go back to the homepage of Arkham and also to the Gotham City Municipal site http://www.gothamcitymunicipal.com/
. This might have already been talked about but I don't remember hearing about it anywhere.
